Before I got my Galaxy Nexus, I was a die hard user of GO Launcher EX. I was actually reluctant to try it at first, but a good friend of mine basically forced me to use it for a day, after which, I never looked back (Thanks, Chris!). I can't imagine having a pre-ICS phone without installing GO.

Now, the GO Team has brought the goodness of GO Launcher EX to Android 3.0+ tablets by way of GO Launcher HD.

Okay, so Redditastic isn't technically an app, but it is a pretty sweet widget that lets you throw your favorite subreddits on one of your homescreens. Unfortunately it's only currently available for devices running Honeycomb or ICS, and it probably won't see any previous builds of Android simply because scrollable widgets aren't supported by them unless you use a custom launcher. That being said, if you do own a supported device, this Reddit widget is definitely one to check out.
